Ash meets a strange old man named Flint, who instructs him in the etiquette of Pokémon training and the rules of the Pokémon League. To enter the League, trainers must collect badges from gym leaders, like the gym in Pewter City run by Brock. Ash quickly challenges Brock to a match and loses. After intense and strange training from Flint, Pikachu battles again and wins, earning Ash a Boulder Badge and a new friend - Brock.
